The Mutiny Adds Online Co-op for Up to Four Players in V1 Update

Solo developer Mach3 has shipped online co-op for The Mutiny, allowing up to four players to join a shared world via a join code and survive together across two existing modes.

What changed

• Online co-op for up to four players, accessible from the main menu alongside the existing offline mode
• Both modes supported: Open World and Horde are playable solo or in co-op
• Per-player character customization — body, face, hair, skin, outfit, and armor — visible to all other players
• Fully synced world state: zombie kills, blood, hit sounds, loot, containers, doors, lanterns, and world pickups are shared
• Co-op death system: when a player dies, their body drops, gets fed on, and reanimates as a zombie wearing their gear — which teammates can hunt and loot
• The map is described as small for now, with expansions planned monthly

Coming later

The announcement flags several features not yet present: persistent online worlds that save between sessions, drop-in/drop-out play, reconnect functionality, and account-based characters that carry across devices, alongside quality-of-life fixes.

For players who have been running solo, co-op fundamentally changes the risk calculus — death is no longer a private setback but a public spectacle that arms the horde with your own equipment.
